Hi everyone, I am usually on this site to drool over purses....but I thought I would come to this section to ask a few questions.... I will be graduating University in April & for my graduation gift from my parents, they want to get me a classic pair of diamond studs that i can wear forever. I know I want screwbacks & a platinum setting....& each earring to be 0.40 - 0.60 carats each. My questions are..... -Where do I start? I know just walking into any jewellery store & buying a pair can be costly. -Is it better to buy the diamonds loose to save money? -I know "D" is colorless...but what is a good color range for the size I want? -Is there an awesome place to buy online that is reputable? Thanks! I am looking forward to your answers & would love to see your pics!
